Weird and annoying but not huge issue.
I have a Pentax K-3 III which can utilize Multi Auto White Balance
Relevant EXIF from RAW or processed JPG file is:
WhiteBalance : Multi Auto
When I use DxO to process as JPG and upload to Flickr, it reports it as AUTO White balance. I am told this is because Flickr only understands AUTO vs MANUAL. That is fine.
When I use Pentax DCU to process as JPG and upload to Flickr, it reports it as MANUAL white balance.
I have run exiftool -s against both files and both still retain WhiteBalance : Multi Auto, but a diff against both files shows a lot of changes, presumably mostly due to stuff put in there by the Post processor.
I dislike mysteries. Is there a way to determine what part of the DCU EXIF is confusing Flickr?
I do know that I have to run exiftool "-lensmodel<lenstype" to gets lenses in to Flickr due to Pentax writing lens info to Maker Notes vs. EXIF and that DCU does not write that into EXIF. This seems different since the tag is there.
Thanks!
Can you post an example file? Both the original and the DXO altered version?
It would also be worth checking which WhiteBalance tag is set. There's EXIF:WhiteBalance and then the Pentax MakerNotes also has a WhiteBalance tag. Run the command in FAQ #3 (https://exiftool.org/faq.html#Q3) to see duplicate tags and the groups they belong to.
Flickr uses exiftool (https://code.flickr.net/2012/06/01/parsing-exif-client-side-using-javascript-2/) on backend and probably doesn't use the options used in FAQ #3 (Duplicates and Groups).
The reason Flickr only has Auto/Manual as options is probably because those are the only valid values for the EXIF:WhiteBalance tag. I don't think Flickr reads the MakerNotes in the file, though I haven't tested this.

Original is too large (40 MB) but I will attach the exiftool -s data text output
DxO: https://www.flickr.com/photos/always_reboot_before_calling_it/52107248878/in/dateposted/
DxO then DCU: https://www.flickr.com/photos/always_reboot_before_calling_it/52107738180/in/dateposted/

Ran that command and diffed against -s itself. I do know that MakerNotes for lenses are not read by Flickr.

Aha!
I ran that command against the DxO file that reports as AUTO [Attached dxo_exif.txt]
[ExifIFD] WhiteBalance : Auto
I also ran that command against the DxO --> DCU file that reports as MANUAL. [Attached dcu_exif.txt]
[ExifIFD] WhiteBalance : Manual
DCU changed it?
OK, exiftool -WhiteBalance=Auto [the filename] fixes it.
